Best stain remover

Tipped off by the comprehensive research at America’s Test Kitchen, I’ve found that the best — really the only — stain remover for laundry that really works is sodium percarbonate, which is a powder you need to mix in water before each use. (No liquid spray works nearly as well.) You then soak garments for 6 hours and wash. It completely removes just about any food stain, even stale ones. There are generic versions available but a proven brand of percarbonate is OxiClean Versatile Stain Remover. — KK
